Overview
Large CFA auger order built in-house: 10 x 300 dia, 10 x 350 dia, 5 x 400 dia, and 5 x 450 dia, each size with four matching cutting heads per string of auger sizes.
Batch breakdown
- 10 x 300 dia augers
- 10 x 350 dia augers
- 5 x 400 dia augers
- 5 x 450 dia augers
- 4 cutting heads per size (16 total)
- 150mm dia parallel male/female hex couplings manufactured in-house
- Flights pressed in-house for consistent profile
Scope & Methods
- Fabricated 30 CFA augers across four diameters with consistent pitch and alignment.
- Built 16 cutting heads (four per size) to match auger diameter and site requirements.
- Pressed the flights in-house to keep pitch and profile consistent across the batch.
- Manufactured 150mm dia parallel male/female hex couplings in-house.
- Prepared the batch for dispatch as a matched set of augers and heads.
- Fully hardfaced for added wear resistance over zig zag methods, cutting heads have wear blocks added to the first two flights for extra protection.
Highlights
Batch Consistency

Production Ready
- All sizes completed in one coordinated run to reduce lead time.
- Finished sets staged for rapid load-out and delivery.
Outcomes
- 30 CFA augers and 16 cutting heads delivered as a full-size set.
